Post a series that has a sibling complex

Boku wa Imōto ni Koi o Suru

zero and ichiru.... i dont kno why no one did post this...this is an obvious answer...

জীবন্ত that has a sibiling complex is always আরো to ecchi anime.. don't আপনি think?

Haru & Sora - Yosuga no Sora

At the moment, I can only think of ones where the older অথবা younger brother is very very picky about whom his পছন্দ অথবা only brother is dating অথবা makes বন্ধু with. Heh...Where I live it's considered weird if আপনি don't at least pretend to hate your siblings.

Hunter x Hunter (not really that apparently until much further into the manga. the জীবন্ত hasn't even gotten that far yet).

Kusatta Kyoushi no Houteishiki.

Challengers / Koisuru Boukun.

The guy definitely had a sister complex lol.

জিন তামা
